WINDOW-OPERATING. DEVICE.

Specification of Letters Patent Application filed June 1,1916. SerialNo. 101,073.

To all whom it may concern:

Be it known that I, CLARKE P. POND, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Window-Operating Devices, of which the following is aspecification.

One object of -my invention is to provide comparatively simple andsubstantial mechanism for swinging one or a series of pivoted sashes 0rventilators on their sup ports to open or close them, the arrangement.

of the parts being such as will allow of the accurate and inexpensiveconstruction and erection of such mechanism as well as its convenientoperation.

The invention also contemplates a novel arrangement of supportingstructure, levers,

and connections, assembled to form mecha-.

Figs. 4 and 5 are respectively a plan and' a front elevationillustrating the detail construction of my operating mechanism;

Figs. 6 and 7 are-respectively a plan and an elevation of a slightlymodified form of the invention;

Fig. 8 is a perspective view of one of the levers forming part of thedevice shown in Figs. 6 and 7 I Fig. 9 is an elevation, partly insection, of the lever-connecting link employed in that -lt'orm of myinvention shown in Figs. 4 and 5; and

Figs. 10 and 11 are horizontal sections on the line 10-10 and 1111,respectively, Fig. 9. p

In the abov drawings 1 and 2 represent two sets of sashes mounted oneabove the other and supported to swing on; pivots 3 of which thosebelonging to any one set of sashes are placedat the centers of the sidesor ends thereof. 4

Each set of sashes, as shown in Fig. 3, has projecting from it, adjacentits pivot, a plate or casting 4 constituting an operating arm and thearm at each side of the sash 1 is connected to the corresponding arm ofthe sash 2 below it by-a bar 5 so that the two sashes natu "ally swingtogether.

For opening and closing the sashes I provide a lever mechanismpreferably mounted on a supporting framefi having approximately the formof two members extending at right-angles to each other and convenientlyattached to the window frame between and to one side of the two sashesby screws or any other suitable means, so that its members he in a planeparallel to that of the sash frame. r

The vertically extending memberof sait frame 6 has pivoted to its upperend a lever consisting of two arms 7 and 8 parallel to each other andmad in a U-shaped form; the pivot being horizontal. The latter of thesearms is pivotally connected tothe ad- Patented May 29, 191?.

jacent operating bar 5 of the sash while the outer extremity of thesecond member of the frame 6' so that it is free to swing in asubstantially vertical plane.

As shown in Fig. '1, there is a pair of levers and their connecting linkcarried on a frame, 6 at each side of the sashes 1 and 2, and foractuating this mechanism I provide suitable means such as that shown inmy Patent No. 886,851, datedMay 5th, 1908.

In the present instance I have illustrated two horizontally extendingparallel rods or bars 13 and 1a which may be moved in oppositedirections and to one of these is pivotallyconnected the second arm. 12of the second lever which swings in a horizontal plane adjacent theleft-hand one of the bars 5. Similarly an a'r1n12 ofthe horizontallever'at the right hand end of thesashes is tween the arms -7 and '11and the link 1.0 are 10 are made forked and the branches of each forkare connected by a suitable pivot pin 15 which has fixed to its centralportion a spherical bearing structure 16. In the present case theadjacent extremity 17 of the lever arm is turned at right-angles to thebody thereof and is perforated to receive this ball-bearing.

Similarly the pivot 18 at the opposite end of the link 10 carries a ballbearing 19 fitted into a perforation in the arm 7 of the verticallymoving lever. With this arrangement of parts there is no binding'betweenthe link and the two levers when these are moved in any of theirpossible positions and it is noted that the turned-up end 17 of thelever 11-12 extends in a' plane inclined to the center-line of the arm11 as shown in Fig. 10.

Under operating conditions the simulta neous movement of the rods 13 and14L in opposite directions causes a simultaneous swinging of the levers11-12 on their pivots and if the sash be closed, the levers 78 are bothswung downwardly on their pivots by power transmitted from the levers11-12 through the links 10. As a consequence there is a downward forceexerted on the projecting operating arms 4 of both sets of sashes andthese latter are caused to swing on their pivots from their closed totheir open position.

With this arrangement of parts the greatest leverage or opening forceoccurs when the sashes are closed or in contact withthe window frames,the movement being relatively slow but powerful and decreasing in forceasthe sashes are opened. In some cases, however, I may construct theoperating mechanism as shown in Figs. 6, 7 and 8. in which case theangle frame 6 has pivoted to the extremity of one of its arms a h0rizontally swinging lever 1112 The arm 11 of this lever is connectedthrough a link 10 with one arm 7 of the vertically swinging lever whosesecond arm extends preferably at an acute angle to said first arm. Asbefore, the link is connected to two levers through ball joints and itis noted that as the lever 78 is moved from the position shown in fulllines to that shown in dot, the pull or force exerted upon its arm 8"increases. This particular form of the invention is designed for theoperation of sashes which are pivoted or hinged to their supportsadjacent their upper ends so that it meets the increase of loadresulting from the opening of the sashes, with an increase of leverage.

I claim 1. The combination in a sash operating device of a supportingframe consisting of two members substantially at right-angles to eachother; a lever mounted on one mem ber of the frame and movable on ahorizontal axis; and a second lever mounted on the other frame memberand free to swing on a vertical axis; with means for operativelyconnecting said levers.

2. The combination in a sash operating device of a supporting frameconsisting of .two bars extending substantially at rightangles to eachother; a lever pivoted to one member adjacent the free end thereof andmovable on a horizontal axis; a second lever pivoted adjacent the freeend of the other frame member and movable on a vertical axis; with meansfor operatively connecting said levers.

3. The combination of a pivoted sash; a lever having an arm connectedthereto and free to move on an axis parallel to the sash pivot; a secondlever pivoted to move on an axis at right angles to that of the firstlever and having an arm connected to a second arm of the first lever;with an operating member movable in either of two directions andconnected to the second arm of the second lever.

1. The combination of a plurality of sashes; a bar connecting saidsashes; a lever pivoted to swing on a horizontal axis and having an armconnected to said bar; a second lever pivoted to swing on a verticalaxis; a link connecting the second arm of the first lever with one armof the second lever; a power actuated member movable in a horizontalline; and means for connecting said member with the second arm of thesecond lever.

5. The combination of sash frame; a sash pivoted therein; a frameincluding two members at right-angles to each other and mounted on thesash frame adjacent two sides of the sash; a lever mounted on said oneof said members and free to swing on a horizontal axis; means forconnecting one arm of said lever to the sash; a second lever pivoted tothe second member of the frame and free to swing on a vertical axis; alink connecting the second arm of the first lever with an arm of thesecond lever; a power actuated operating lever mounted to move adjacentthe sash; and means for connecting said member with the second arm ofthe second lever.
